ROBERT B. PARKER, JR., OF GLOUCESTER, MASSACHUSETTS.

WATER-REGULATOR;

To all whom it may concern 7 Be it known that I, ROBERT B. PARKER, J12, a citizen of the United States, residing at Gloucester, in the county of Essex, State of Massachusetts, have invented certain new and useful Improvements in Water-Regw lators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same. 7

My invention relates to new and useful improvements in devices for regulating the depth of water in bath tubs and the like and the object of my invention is to improve the construction and increase the efficiency of devices of the above described type.

A further object of my invention is to provide a device which may be readily attached to or detached from a water faucet of the customary form and which will automatically check the flow of water into the tub after the water has reached a predetermined depth therein.

ith these and other objects in view, my invention will be more'fully described, illustrated in the drawings which show a preferred embodiment of my device and then specifically pointed out in the claims which are attached to and form a part of this application.

In the accompanying drawings, Figure 1 is a side elevation of the device as attached to a conventional form of faucet. Fig. 2 is a vertical longitudinal section showing the device open in position to permit the passage of the water therethrough. Fig. 3 is a similar section showing the position of the parts when the flow of water is cut off. Fig. l is a transverse section on the line ll of Fig. 1.

Referring more specifically to the drawings, in which similar reference, numerals designate corresponding parts throughout, 1 designates in general the casing of my improved device which as shown, is substantially rectangular in shape and is provided with an open lower end 2. This casing may be constructed of any preferred material but is preferably formed of metal which may be cast in one piece or formed of sheet metal having its seam fastened in any preferred Water-tight manner as by soldering. The upper end of this casing is closed by a flexible water tight member 3 preferably formed of rubber and this clo- Specification of Letters Patent.

sure 3 is provided with a centrally located aperture 4 adapted to receive the end of a faucet, conventionally shown at 5. This aperture is preferably formed of less diameter than that of the faucet in such a manner that when the member 3 is forced over the latter a strong water-tight joint is formed. As an additional means for securing the device to the faucet I have provided the easing at opposite sides and adjacent its upper end with tapped bores 6 through which extend the threaded ends of set-nuts 7, which ends are provided with any suitable form of clamping head 8 while the other ends are provided with gnarled heads 9 by means, of which the nuts may be readily tightened to secure the device in place; The rear face of this casing is provided intermediate its length with a narrow transversely extending slot 10the ends of which are enlarged to provide space for guides 12 and 13 the lower ends of which are secured against the inner faces of the side walls of the casing while their upper ends extend outwardly through the enlarged portions of the slot and upwardly therefrom to 'form an inclined guide way. As shown each of these guides consists of a substantially U- shaped member the bight portion of which forms the guide and these bight portions are apertured' to form bearings 14 in which is journaled a roller 15. Slidably mounted in these guides is a cut-off platel6 which is preferably formed of sheet metal and which in its lowered position extends completely across the casing to form a transverse partition wall, the lower end of this plate when so positioned being reinforced and supported by means of a strip 17 which is secured to the opposite wall of the casing and which registers with and forms a continuation of the guides 12 and 13. When drawn outwardly and upwardly to its full extent the lower end of this plate extends just within the casing and is preferably weighted as at 18 by which means when released it immediately slides down the guides to its lowered position. This cut-ofi plate, slot and guides, are so proportioned and positioned as to permit of the ready movement of the plate in the guides while at the same time they form a practically watertight partition across the chamber as best shown in Fig. 3 of the drawings.

As a means for governing the valve or cut-01f thus formed I have provided a cord plate in its outer or open position.

19 one end of which is secured to the outer end of the cut-off plate while the other end is passed over the roller and provided with a hook 20 adapted to engage with a float 21, the weight of this float being such that when unsupported it will maintain the cut-off I V This cord is preferably provided throughout its length with a plurality of spaced apart hooks similar to the hook 20, any one of which is adapted to engage the weight in order that the device may be readily regulated for various depths of water as will be hereinafter apparent.

In'operation the device is secured to the faucet as described and the float is suspended upon that hook which will allow it to cut oif the flow of water when it rises to the height above the bottom of the tub equal to the depth of the water desired, the

cut-off plate being in open position as shown in Fig. 2. The faucet is then turned on in the customary manner the waterpassing downwardly through. the casing and out of its open end as will be readily understood. When the water is raised in the tub to a djefpth sufficient to support the float the cutplate because of its weight moves clownwardly and inwardly to close the casing and thus prevent further flow of water therefrom. As shown in Figs. 2 and 8 the lower end of this plate is preferably weighted by means of a transversely extending bar of metal secured to its upper face and it will be apparent that as soon as the platehas moved a sufficient distance to bring this bar under the water flowing from the faucet the striking of the water against it will assist in quickly closing the same.

From the foregoing description it will be apparent that I have provided a simple and efficient cut-0E and one which is automatical in its action.

It will be understood that I do not wish in any way to limit my device to the regulation of the depth of the water in a bath tub as it may be employed in any place and for any purpose in which liquid is supplied through a pipe or faucet to a receiving vessel.

What I claim is l. A device of the character described, comprising a casing open at its lower end and provided with means for water tight engagement with a faucet at its upper end, i

a cut-off plate slidable transversely across said casing intermediate its length, a cord connected to said plate, and a float connected to said cord.

2. A device of the character described comprising a casing open at its lower end and a sheet rubber closure at its upper end provided wlth a faucet recelving aperture, means for clamping sald casing to a faucet,

one side of said casing being provided intermediate its length with a transversely eX- tending slot, guides extending upwardly and outwardly through said slot, a cut-off plate slidable in said guides and through said slot, a roller journaled in the outer In testimony whereof, I afliX my signa-' ture, in presence of two witnesses.
